Re-posted from the Lake View & Black Hawk Lake, Iowa Facebook page

"Last week the DNR lake water tests showed an elevated level of microsystins (a.k.a. blue-green algae or cyanobacteria) at Black Hawk Lake. The weekly test results are posted every Friday on this site: http://www.igsb.uiowa.edu/wqm/​Beaches/BeachMapState.htm. Warning signs have been posted at the local beaches. The levels can change quickly, so be sure to check the DNR website for the latest information."
